MATTER Anything that has mass and takes up space

2. A change in physical properties, but not the identity of the material
Box 1 (top left)
A change in physical properties, but not the identity of the material
Example: ice → water → steam (all H2O)
Change can be reversed

3. A change to any of these properties:
Box 2 (top right)
A change to any of these properties:
Observable – color, shape, structure, size, texture
Measurable – weight, mass, length, density, volume
States of matter – solid, liquid, gas, (plasma)
Solubility (dissolving) – ex: salt & water

4. A change in which a new substance is formed
Box 3 (bottom left)
A change in which a new substance is formed
Change cannot be reversed (chemical bonds are broken, original substances are gone)
Caused by reacting with: oxygen, light, water, heat, electricity, or other elements

5. Signs of a chemical change: (evidence of a new substance being formed)
Box 4 (bottom right)
Signs of a chemical change: (evidence of a new substance being formed)
Formation of a gas = bubbles/fizzing/expanding
Change of temperature
Producing light, smoke, or sound
Change in color
Formation of a precipitate

6. Box 5 (back top) Law of Conservation of Mass:
Matter is not created or destroyed in a chemical reaction.
